Programmable Logic Controllers

So I do a lot of programming for PLC's, right now just in school, but before it was at work as well. These things can do everything with the right programming, and was just curious to see if anyone out there utilizes a Plc for their tank?
My next tank build, yes I just started a 180 a year ago, but my parents are moving to their cabin in Wisconsin and leaving me and my bro the house here in shueyville. Perfect time to start planning for a bigger build. 
My new tank will be roughly 500 gallons, give or take a few. I want to incorporate a Plc into this build. Hook it up to everything, humidistat to control fans and ventilation, float switches for water, automated water changes, feed cycles, the WHOLE WORKS. 
Who has done this, and if you guys know of anyone who has can you direct me to them or a thread?
Thanks!

 

Haha, yea I can program plcs have the software as well. Kind of a joke if you ask me, I can program a Plc but not my apex... Laugh!!! Thanks for the link bud!

 

PLC's are pretty reliable man. Allen Bradley micro logix 1000 analog would be a good start. Even a SLK 500, gives me a ton of options. It's just like relying on your apex to do the work, except all your inputs and outputs are controlled by a 24 volt source, to kick on and off your 120v outputs. 
As with everything automated, there's a chance they fail. From what I've seen and experienced tho, they are pretty reliable imo

 

Where do you work potter, if you don't mind me asking. I graduate in 5 weeks, going to be looking for some work!

 

Get in touch with the guys at your work, and see if they can explain any questions you have. If you can write schematics, you can write a Plc program. Same concept just a few more hidden tricks! I also have a ton of books on PLC's that you could possibly borrow if you're interested. Once I'm done with them of course /DesktopModules/ActiveForums/themes/_default/emoticons/smile.gif

 

Factory hardened, you bet! Those things can take a lickin and keep on tickin. Good thing is, if you ever lose your programming, as long as you saved a backup file, which rslogix 500 creates backup files automatically for you, you can revert to those if something happens. This is definitely going to be incorporated into my next tank build for sure. I'm excited. This is going to be a big build, actually probably a few years in the process. Good things happen to those who wait, and I'm going to be extra patient with this one. Piece by piece!

 

Only downfall is that you need RSLynx and RSlogix 500, for people who don't have access to that as of now, those programs are EXPENSIVE!
